You have to start somewhere when looking for life away from Earth. Many #NASAExplorers look for places with water ice, including distant moons like Enceladus and Europa. This week, we’re traveling away from our home planet to investigate ice in the solar system.
Timelapse of the Russian Progress MS-10 cargo spacecraft launched on 16 November 2018 at 18:14 GMT from Baikonur cosmodrome, Kazakhstan, taken by ESA astronaut Alexander Gerst from the International Space Station.
The spacecraft was launched atop a Soyuz rocket with 2564 kg of cargo and supplies. Flying at 28 800 km/h, 400 km high, the International Space Station requires regular supplies from Earth such as this Progress launch. Spacecraft are launched after the Space Station flies overhead so they catch up with the orbital outpost to dock, in this case two days later on 18 November 2018.
The images were taken from the European-built Cupola module with a camera set to take pictures at regular intervals. The pictures are then played quickly after each other at 8 to 16 times normal speed. The video shows around 15 minutes of the launch at normal speed.
The Progress spacecraft delivered food, fuel and supplies, including about 750 kg of propellant, 75 kg of oxygen and air and 440 l of water.
Some notable moments in this video are:
00:07 Soyuz-FG rocket booster separation.
00:19 Core stage separation.
00:34:05 Core stage starts burning in the atmosphere as it returns to Earth after having spent all its fuel.
00:34:19 Progress spacecraft separates from rocket and enters orbit to catch up with the International Space Station.

Europe’s Vega launch vehicle operating from Europe’s Spaceport in Kourou, French Guiana, has a flawless record.
Vega serves a wide range of missions and payload configurations, responding to different market opportunities. It is the ideal launcher for most scientific and Earth observation missions, benchmarked to loft 1500 kg into a 700 km-altitude circular orbit at 90° inclination.
Based on this success a more powerful #Vega, Vega-C, now in development is set to launch in mid-2019 offering greater performance at no additional cost.
Vega-C shares technology with Europe’s other new launcher Ariane 6. The P120C solid fuel motor will be used as the first stage for Vega-C and two or four will be used as strap-on boosters for Ariane 6.

Orion is NASA’s spacecraft for carrying astronauts on exploration missions to the Moon and beyond. When Orion returns to Earth from space, it will be slowed by parachutes before splashdown. Here, NASA’s recovery team and the U.S. Navy practice recovering a test Orion capsule from the ocean waters. Bonus: stunning views of the sunset in the Pacific off the coast of California!
This footage was captured on Nov. 1, 2018, during Underway Recovery Test-7 (URT-7) — one in a series of tests that NASA’s Exploration Ground Systems Recovery Team and the U.S. Navy are conducting: https://go.nasa.gov/2Ph6Mnr. These tests verify and validate procedures and hardware that will be used to recover the Orion spacecraft after it splashes down in the Pacific Ocean following deep space exploration missions.
Space weather describes the changing environment throughout the Solar System, driven by the energetic and unpredictable nature of our Sun. Solar wind, solar flares and Coronal Mass Ejections can result in geomagetic storms on Earth, potentially damaging satellites in space and the technologies that rely on them, as well as infrastructure on the ground.
ESA’s future Lagrange mission will keep constant watch on the Sun. The satellite, located at the fifth Lagrange point, will send early warning of potentially harmful solar activity before it affects satellites in orbit or power grids on the ground, giving operators the time to act to protect vital infrastructure.
ESA is now working with European industry to assess options for the spacecraft and its mission, with initial proposals expected early in 2020.
Our star dominates the environment within our Solar System. Unpredictable and temperamental, the Sun has made life on the inner-most planets impossible, due to the intense radiation and colossal amounts of energetic material it blasts in every direction, creating the ever-changing conditions in space known as ‘space weather’.

NASA Explorers is a new digital series that takes you inside the space agency and follows the pioneers, risk-takers and experts at the front line of exploration. Season 1, “Cryosphere,” joins NASA scientists on their journey to the frozen ends of the Earth as they study our rapidly changing world from satellites, planes and boots on the ground. The Cryosphere is a place we all depend on, but many of us will never go to. As temperatures rise, the frozen regions of Earth are changing rapidly. NASA scientists are locked in a race against time to understand our shifting climate and how it affects life on Earth.
Can you spot the sharp-angled, rectangular iceberg? This footage (partially sped up) is from an Oct. 16, 2018 flight over the northern Antarctic Peninsula by our Operation IceBridge DC-8 aircraft. Mission Scientist John Sonntag provides commentary. More: https://go.nasa.gov/2JdEy71
Operation IceBridge is NASA’s longest-running aerial survey of polar ice. During the survey, designed to assess changes in the ice height of several glaciers draining into the Larsen A, B and C embayments, IceBridge senior support scientist Jeremy Harbeck saw a very sharp-angled, tabular iceberg floating among sea ice just off of the Larsen C ice shelf. A photo of the iceberg (seen at right) was widely shared after it was posted on social media.
A look at the elements that make up the European service module that will provide power, water, air and electricity to NASA’s Orion Moon module.
Made in Europe the service module is integrated in Bremen, Germany, from where it will be shipped to NASA’s Kennedy Space Center in the USA for testing and getting ready for launch.
Inside the Service Module, large tanks hold fuel as well consumables for the astronauts: oxygen, nitrogen and water.
Radiators and heat exchangers keep the astronauts and equipment at a comfortable temperature, while the module’s structure is the backbone of the entire vehicle, like a car chassis.
The European Service Module is built by main contractor Airbus, with many companies all over Europe supplying components.
Orion will eventually fly beyond the Moon with astronauts, the first time a spacecraft will support humans with European hardware will also be the farthest humans ever travel from Earth. The first mission – without astronauts – is getting ready for launch in 2019.

This visualization uses a digital 3D model of the Moon built from global elevation maps and image mosaics by NASA’s Lunar Reconnaissance Orbiter mission. It was created to accompany a performance of Claude Debussy’s Clair de Lune by the National Symphony Orchestra Pops, led by conductor Emil de Cou, at the Kennedy Center for the Performing Arts in Washington, DC, on June 1 and 2, 2018, as part of a celebration of NASA’s 60th anniversary.
Clair de Lune (moonlight in French) was published in 1905, as the third of four movements in the composer’s Suite Bergamasque, and unlike the other parts of this work, Clair is quiet, contemplative, and slightly melancholy, evoking the feeling of a solitary walk through a moonlit garden.
The visuals were composed like a nature documentary, with clean cuts and a mostly stationary virtual camera. The viewer follows the Sun throughout a lunar day, seeing sunrises and then sunsets over prominent features on the Moon. The sprawling ray system surrounding Copernicus crater, for example, is revealed beneath receding shadows at sunrise and later slips back into darkness as night encroaches.
